dB Calculator Plus vs Decibel calculator使用状況と統計

dB Calculator is a physics/math calculator designed to find sound pressure level (SPL) and sound intensity level (SIL) in decibels quickly and easily. Features: - Instant calculation - Results are copyable to other apps - Formulas are included as a reference - Support up to 16 decimal places Sound pressure level (SPL) SPL is a ratio of the absolute sound pressure to a reference level, usually the Threshold of Hearing, or the lowest intensity sound that can be heard by most people. SPL is measured in decibels (dB) due to the broad range of intensities we can hear. Formula: SPL = 20 * log (P/Pref) Where: SPL - is the sound pressure level in dB P - is the sound wave pressure, measured in pascals Pref - is the reference value of sound pressure, typically assumed to be equal to 0.00002 Pa Sound intensity level (SIL) Sound intensity is defined as the sound power per unit area, typically measured in the air at a listener's location. The basic units are watts/m² or watts/cm². Formula: SIL = 10 * log (I/Iref) Where: SIL - is the sound intensity level in dB I - is the sound intensity in watts per squared meter Iref - is the reference value of sound intensity, typically assumed to be equal to 10⁻¹² W/m² Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.

Sound levels are usually expressed in a logarithmic scale called the decibels (dB). The decibels cannot be added or subtracted directly. Each operation between decibel values requires to convert the sound level back to a linear scale using an antilog function. The dB calculator app allows the direct addition or subtraction of dB levels. The app uses the following formula: A + B = 10*LOG10(10^(A/10) + 10^(B/10)) For instance, 5dB + 5dB returns 8dB (3dB is added when doubling the sound level) or 1dB + 2dB = 4.5dB.
